IPC: G10K11/16
Filed: 1993-06-07
Abstract: PURPOSE:To silence the noises generated from various kinds of household electrification products using motors with simple constitution without mounting the silencer on the respective household electrification products. CONSTITUTION:A noise pulse detecting section 3 takes out only the noise pulses NP having a correlation with noises, such as revolving sounds of motors and electromagnetic sounds, emitted from the household electrification products included in a commercial AC power source via a receptacle plug 2. Error microphones 81, 82 are mounted in the positions where the noises in a room are heard. These microphones detect the levels of the residual noises and convert these levels to residual noise signals SN1, SN2. A control section 11 and a signal processing section 13 form additive sound signals in accordance with the noise pulses NP and the residual noise signals SN1, SN2 and respectively supply these signals to additive sound source speakers 141, 142 disposed in correspondence near to the error microphones 81, 82. As a result, the additive sound source speakers 141, 142 radiate the additive sounds of the antiphase from the phase of the waveform components of the noises emitted from the household electrification products in accordance with the additive sound signals respectively inputted thereto and, therefore, the noises emitted from the household electrification products in the noise hearing positions in the room are silenced by the additive sounds.

IPC: H01S5/00
Filed: 1986-06-11
Abstract: PURPOSE:To make the characteristic uniform by forming a highresistance semiconductor crystal film having a larger band gap than the photon energy of a laser beam on the surface of a laser resonator on a semiconductor laser crystal wafer with a groove formed therein. CONSTITUTION:A resonator surface forming groove 5 and a pellet separating groove 4 which form a resonator surface 3 are formed by an RIE method or a chemical etching method on the surface of a semiconductor laser crystal wafer having a stripe-shaped groove 2 for controlling an oscillation mode and a double hetero junction layer on a GaAs substrate 1. Next, an undoped AlGaAs film 6 having a higher mixed crystal ratio than an active layer, i.e. a wider band gap than this layer, is made to grow epitaxially by an MOCVD method. On the occasion, oxygen and water in an apparatus are taken in to make the AlGaAs film 6 be a semi-insulative high-resistance layer. Thereby an electric short circuit of a double hetero junction can be avoided. Besides, no astigmatism occurs and a reflection loss is small since a high band gap layer is thin. Thus, the characteristic of a laser element becomes uniform.
